WESLEY IDO'IY, OF 6SHKOSI-I, WISCONSIN.

AUTOMOBILE-JACK.

To all whom it may concern Be it known that I, WESLEY Dory, a citizen of the UnitedStates, residing at Oshkosh, in the county of l/Vinnebago and State of Wisconsin, have invented certain new and useful Improvements in Automobile-Jacks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This device has for its object to provide a simply constructed and inexpensive automobile jack of the type designed to relieve strain from the tires of the vehicle when the same is standing within a garage or the like, and to this end the invention resides in the unique construction hereinafter fully de scribed and claimed, the descriptive matter being supplemented by the accompanying drawings which constitute a part of this application and in which:

Figure 1 is a front elevation of the improved ack; Fig. 2 is a. rear elevation thereof; Fig. 3 is an edge view showing the man ner in which the jack is applied; Fig. 4 is a similar view illustrating the jack in operative position; Figs. 5 and 6 are horizontal sectional views on the planes of the lines 5-5 and 6-6 of Fig. 1; and Fig. 7 is a vertical section on the plane of the line 77 of Fig. 1.

In the drawings above briefly described, the numeral 1 designates a U-shaped supporting frame formed of L-iron or steel, the vertical arms of said frame preferably including upper sections 2 which are adjustably secured to the lower fixed sections 3 by means of bolts 4 passed through bolt holes 5 in the contacting flanges of the upper and lower sections. The upper end of one flange of each section 2 is bent into the plane of the other flange thereof so as to provide said sections with flat terminals 6.

A lifting frame 7 is pivotally connected with the frame 1, said lifting frame being formed of a single length of L-iron or steel bent into the form of a U of less size than said frame 1.

The upper end of one flange of each arm of the frame 7 is bent into the plane of the other flange thereof to form said frame with flat terminals 8 contacting with the inner sides of and extending above the terminals 6, rivets or the like 9 being passed through the rear edges of the terminals 8 and through Specification of Letters Patent.

the terminals 6 to gether.

A. hub rest extends between the front edges of the terminals 8 at the upper ends thereof as shown, said rest preferably consisting of rivet 10, a metal roller 11 surrounding said rivet, and a cushioning sleeve 12 of rubber or the like extending around said roller.

By constructing the improved jack in the manner shown and described it will be inexpensive to manufacture and may thus be marketed at a minimum cost. Regardless of this, however, the device will be etlicient and durable and when applied will take all strain from the tires of the vehicle in connection with which it is used.

In applying the. improved jack the lifting frame 7 is swung upwardly to the required amount for. permitting the hub rest to be inserted beneath the hub of the wheel as shown in Fig. 3. The frame 7 is then swung downwardly until it nests within the angular arms of the frame 1, this movement serving to raise the wheel as will be clear from Fig. 4. As also depicted in this figure, the hub rest swings outwardly beyond dead center or in other words beyond the rivets or pivots 9 and thus the frame 7 is held in operative position without the use of any locking means.

In the drawings certain specific details have been shown for illustrative purposes and in the preceding such details have been described. It is to be understood, however, that numerous changes in form, proportion and minor details may be made without sacrificing the advantages of the invention as claimed.

1 claim:

1. A ack comprising a U'shaped supporting frame whose arms are formed of L-iron or steel, the upper end of one flange of each arm being bent into the plane of the other flange thereof to form flat terminals greater in width than said arms, a U-shaped lifting frame whose arms are also formed of L-iron or steel capable of nesting in the angles of the first named arms, the upper end of one flange of each of the arms of said lifting frame being bent into the plane of the other flange thereof to form additional flat terminals greater in width than said arms of the lifting frame, pivots passing through the rear edge of said additional terminals and through the first named terminals, and a hub pivot the two frames torest extending between the front edges of said additional terminals above said pivots. 2. A jack comprising a length of L-iron or steel bent into the form of a U, a pair of positioned for nesting in the angles'of the aforesaid side bars, one. flange atthe upper end of each armof said lifting frame being bent into the plane of the other flange thereof to. form additional flat terminals greater in idth than the arms of said frame, pivots passing through the rear edges of sald additional terminal and through the first named terminals, and a hub rest extending between the front edges of said additional terminals above said pivots.

In testimony whereof I have hereunto set 7 my hand in the presence of two subscribing Witnesses.
